Foot-pounds per Second to BTUs per Hour Converter

To convert a measurement in foot-pounds per second to btus per hour, multiply the value by 4.626243. The conversion factor comes from the relationship between both units and the watt.

For example, to convert 5 ft·lb/s to btus per hour: 5 × 4.626243 = 23.131214 BTU/h.

A foot-pound per second is an imperial unit of power equal to about 1.356 watts, representing one foot-pound of work performed each second. Rooted in imperial mechanics, the foot-pound per second is the basis from which horsepower was defined — 550 ft·lb/s equals one mechanical horsepower.

Common uses of foot-pounds per second include: Mechanical engineering in imperial units; Deriving horsepower from work rate; Physics work-and-power problems; Legacy machinery specifications.

A BTU per hour is a unit of power equal to about 0.293 watts, used to rate the heating and cooling capacity of HVAC equipment. Derived from the British thermal unit, BTU/h became the standard rating for air conditioners, furnaces, and heat pumps in the United States, where a '12,000 BTU' unit describes one ton of cooling.

Common uses of btus per hour include: Air conditioner cooling capacity; Furnace and heat-pump ratings; HVAC load calculations; Radiator and boiler output.

Here are some common values converted:

1 ft·lb/s = 4.626243 BTU/h 5 ft·lb/s = 23.131214 BTU/h 10 ft·lb/s = 46.262429 BTU/h 50 ft·lb/s = 231.312143 BTU/h 100 ft·lb/s = 462.624287 BTU/h
